to determine the yield stability, adaptability and analysis of the genotype× environment interaction of virginia tobacco, 15 hybrids of tobacco including 10 iranian and 5 international hybrids were evaluated in two different experiments (water stress and normal irrigation) using a randomized complete block design (rcbd) with three replications at two locations including rasht and tirtash tobacc...

A multi-component systems approach is proposed to reduce the risk of oriental fruit fly infestation in ‘Sharwil’ avocados exported from Hawaii into the United States to an acceptable level. This systems approach is based on poor host status, limited distribution and low prevalence. Recent surveys suggest oriental fruit fly populations are naturally low in Hawaii’s small avocado orchards. Mainta...

Oriental bit tersweet (Cc1a.rtru.s or-biculutus), an introduced vine from southeast Asia, has become a serious threat to native forests in the eastern United States. It is typical of many exotic species in that quantitative ecological relationships are unavailable for assessment or management. We devised a rapid survey technique useful for hazard rating and modeled the probability of occurrence...

Oxyceroides gen. nov., including three new species, O. gracilis sp. nov., O. sinica sp. nov. and O. tangi sp. nov. from South China in the Oriental region are described and illustrated. Related genera from other biogeographical realms are briefly discussed. Identification keys to the known Oriental Oxycerini and to the three new species of Oxyceroides are given.

Ginseng is a well-known medicinal plant used in traditional Oriental medicine. In recent decades, ginseng root has gained popularity as a dietary supplement in the United States. Ginseng has also been commonly used in Oriental medicine to treat diabetes-like conditions. The present review discusses the research on the anti-diabetic effects of ginseng and the possible mechanisms of its anti-diab...

Rickettsia typhi and R. felis, etiologic agents of murine typhus and fleaborne spotted fever, respectively, were detected in Oriental rat fleas (Xenopsylla cheopis) collected from rodents and shrews in Java, Indonesia. We describe the first evidence of R. felis in Indonesia and naturally occurring R. felis in Oriental rat fleas.

european corn borer, ostrinia nubilalis hb. is a polyphagous insect, recognizing world widely as the predominant pest of maize. in this research the relative resistance of eleven hybrids of maize was evaluated in a field in agricultural and natural resources research center of moghan. this experiment was conducted in three replicates in a complete randomized block design. for comparison of the ...

Hybrids as various resources have valuable importance in tree breeding. Today, improvement programs by using poplar and willows and their hybrids play basic role in supplying wood and decreasing pressure on natural forests. This research was carried out in order to study inter-generic hybridization possibility between Salix aegyptica and Populus caspica species from Salicaceae to achieve new hy...

This study compared the efficacy of SPLAT-OrB, a new pheromone formulation for oriental beetle mating disruption that can be mechanically applied, with hand-applied plastic dispensers in commercial blueberry fields. Both formulations were tested at 2.5 and 5 g of the major sex pheromone component (Z)-7-tetradecen-2-one per hectare, and evaluated by measuring trap shut-down, mating success of ca...
